F280 Heat Loss & Heat Gain

In Canada, achieving peak energy efficiency and year-round comfort in homes hinges on correctly sizing HVAC systems. That’s where the CSA F280-12 Standard—commonly referred to as F280—comes into play. This nationally recognized guideline outlines a precise methodology for calculating residential heat loss and heat gain. By following F280, builders and HVAC professionals can ensure that heating, ventilation, and air conditioning systems are tailored to the specific needs of each home—avoiding the pitfalls of systems that are too small to perform or too large to operate efficiently.
